The trend of green transformation and carbon emission reduction is driving Vietnamese businesses to gradually replace traditional fuels (coal and oil) with biomass fuel.

The 4 most common biomass fuels used in Vietnam:

1. Wood Pellets

• Raw materials: sawdust, wood shavings, rubberwood, acacia wood.
• Calorific Value: 4,200 – 4,600 kcal/kg
• Moisture Content:< 10%
• Ash Content: <2%

✅ Advantages: stable combustion, low ash content, widely selected by industrial plants, with large export volumes to South Korea and Japan.

2. Rice Husk Pellets

• Raw materials: rice husk from rice milling factories.
• Calorific Value: 3,600 – 4,000 kcal/kg
• Moisture Content: < 12%
• Ash Content: 12–18%
  ✅ Advantages: low cost and abundant supply in the Mekong Delta region.

3. Cashew Shell Biomass

• Raw materials: cashew shells after oil extraction.
• Calorific Value: >4,600 kcal/kg
• Moisture Content: < 12%
• Ash Content: < 3%
  ✅ Advantages: high heat generation, more competitive pricing than wood pellets, and stable year-round supply.

4. Wood Chips

• Raw materials: acacia wood, rubberwood, wood offcuts, tree stumps, and branches.
• Calorific Value: 3,800 – 4,200 kcal/kg
• Moisture Content: 30–50%
  ✅ Advantages: low cost, suitable for large-capacity chain grate boilers and fluidized bed boilers.

Conclusion:

Depending on the boiler type, heat requirements, and fuel budget, businesses can select the most suitable biomass fuel option.
